Cervical spine (C-spine) injuries are the most feared of all spinal injuries because of the potential for significant deleterious sequelae. Correlation is noted between the level of injury and morbidity/mortality (ie, the higher the level of the C-spine injury, the higher the morbidity and mortality). Craniocervical junction injuries are the deadliest.

This article focuses on the uniqueness of and the most common types of traumatic C2 (axis) fractures.
